We have developed a novel sensation interface using galvanic vestibular stimulation
(GVS) (see also Maeda
Lab. in Osaka Univ.). The vestibular system is stimulated by weak current through the electrodes, placed behind the ears. GVS causes lateral virtual acceleration toward the anode, which shifts the sense of balance. The GVS interface can induce lateral walking diverging from intended straight line.

Hold your wavering identity

Based on this GVS technology, we produced an artwork “Save YourSelf !!!” on the subject of wavering identity in the modern society. In our artwork, a tiny doll is floating on the water. An acceleration sensor is integrated into the doll, and the obtained data is sent to the GVS interface. GVS is presented according to the data form the sensor. Any kind of vibration of the doll disturbs the balance of the wearers. When the doll falls over, they feel big swaying sensation. This GVS interaction makes them feel truly connected to the doll. They keep on walking, while holding the tank of water. This artwork is intended to observe and hold your wavering identity (the doll on the water) from the outer perspective.

Beyond the Interface...

GVS technology can be applied not only to the information presentation but also to the field of artistic expressions and entertainments. We hope that the experiences of GVS remind users of how the human perceives and behaves in the world, and it enrichs human life and mind.
